CrossFit® Dark Side: Opinions

4.8/5 (11 Opinions)
Juliana 2 years ago

Fantastic experience: I didn’t think I would have actually improved, but years later, I’m still here and still seeing more and more results. It’s the best workout you could get, and all the coaches are so great at boosting confidence, and making everyone feel welcome.

Fantastic experience: Challenging daily workouts. Knowledgeable & supportive coaches. A welcoming and friendly community. If these things sound good to you, give CF Darkside a try. You won’t regret it!

Fantastic experience: This place has educated and experienced coaches. It's a nice facility with a shower. There are a lot of class times and the people are great ☺

Fantastic experience: Dropped in while in town this week. Amazing experience! Did 2 classes and both coaches were some of the best I've known and I have been to dozens of CF boxes. While its theme is there its not in your face, and the gym is laid out really well. The equipment was in great shape and the programming was genius as well. The community was super welcoming and they made me feel right at home. Would definitely recommend stopping by and checking them out in the San Diego area.
